Mark, a software engineer from Austin, Texas, moved to Medellín in January 2025 on a digital nomad visa arrangement before converting to a Visa M. He had done his research — or thought he had. He knew about Colombia's 183-day rule. What he had not fully internalized was that US citizens carry their tax obligations with them to every country on earth. The United States taxes its citizens on worldwide income regardless of where they live. Mark's Colombia tax situation was not just Colombia's 183-day rule. It was that rule layered on top of: FATCA (Foreign Account Tax Compliance Act) reporting requirements for his Colombian bank accounts, FBAR (FinCEN 114) filing for any Colombian accounts exceeding USD 10,000, the Foreign Earned Income Exclusion (FEIE — IRS Form 2555) potentially exempting up to USD 130,000 of earned income from US tax in 2026, and the interaction between IRS and DIAN obligations after day 183. The United States has no comprehensive double taxation treaty with Colombia — only a limited Tax Information Exchange Agreement (TIEA) signed in 2012. This guide covers every US-specific tax layer for Americans in Colombia: citizenship-based taxation, FEIE, FATCA, FBAR, Social Security implications, and the Art. 11 plan that all US nationals on Visa M must hold from day one.

Citizenship-Based Taxation: The US Tax Obligation You Carry to Colombia
Most countries tax residents — people physically present or domiciled in the country. The United States taxes citizens and Green Card holders on worldwide income regardless of where they live or earn. This is called citizenship-based taxation (CBT), and it means that moving to Colombia does not end your IRS obligation. You must file a US federal tax return every year regardless of whether you have any US-sourced income, and regardless of whether you owe any US tax. Failure to file is a separate violation from failure to pay — late-filing penalties (5% per month of unpaid tax) accrue independently. The IRS Streamlined Filing Compliance Procedures exist for Americans who have been non-compliant — the Streamlined Foreign Offshore Procedures waive most penalties if you certify that non-compliance was non-willful. The baseline: as a US citizen in Colombia, you owe both IRS and DIAN compliance simultaneously after day 183.
The Foreign Earned Income Exclusion (FEIE): Your Main US Tax Tool
The Foreign Earned Income Exclusion (FEIE — IRS Form 2555) is the primary mechanism for avoiding double US taxation on income you earn while living abroad. For 2026 (inflation-adjusted), the FEIE exclusion amount is approximately USD 130,000 — this figure is adjusted annually by the IRS. To claim the FEIE, you must qualify under one of two tests: the Bona Fide Residence Test (you are a bona fide resident of Colombia — established after approximately one full tax year of genuine Colombian residence), or the Physical Presence Test (you have been physically present in a foreign country for 330 full days during any 12-month period). Important: the FEIE excludes earned income (wages, freelance, self-employment) — it does not exclude passive income (interest, dividends, capital gains, rental income). For passive income, the Foreign Tax Credit (Form 1116) is the available mechanism — crediting Colombian taxes paid against US tax liability. Self-employed Americans: you still owe US self-employment tax (Social Security and Medicare — 15.3%) on net self-employment earnings even after applying the FEIE, because FEIE does not cover self-employment tax. The US–Colombia Social Security Totalization Agreement does not exist — unlike the US–Germany or US–France agreements, there is no bilateral instrument to prevent double Social Security contributions.
FATCA and FBAR: Mandatory Financial Reporting
US citizens with foreign financial accounts have two parallel reporting obligations that apply in Colombia. FBAR (FinCEN 114 — Report of Foreign Bank and Financial Accounts): if the aggregate value of all your foreign financial accounts exceeds USD 10,000 at any point during the calendar year, you must file FinCEN 114 annually by April 15 (with automatic extension to October 15). This applies to all Colombian bank accounts — Bancolombia, Davivienda, Banco de Bogotá, Nequi balances above the threshold. Penalties for willful failure to file FBAR: up to USD 100,000 per violation or 50% of account value, whichever is greater. FATCA (Foreign Account Tax Compliance Act — IRS Form 8938 Statement of Specified Foreign Financial Assets): separately required for higher asset thresholds — USD 200,000 on the last day of the year (or USD 300,000 at any point during the year) for US residents abroad. Colombian banks are FATCA-compliant and report US-citizen account holders to the IRS automatically under Colombia's IGA (Intergovernmental Agreement) with the US. Opening a Colombian bank account as a US citizen triggers FATCA reporting on the bank's side — you cannot avoid this. The practical impact: open your Colombian accounts with accurate US citizenship disclosure, keep FBAR records, and file annually.
Day 183 — Colombian DIAN Obligations Begin
After 183 days in Colombia (cumulative within a 365-day period), you become a Colombian tax resident under Art. 10 of the Estatuto Tributario. As a Colombian tax resident, you must: file a declaración de renta (income tax return) with DIAN, declare worldwide income (ingresos mundiales), and apply Colombian tax rates (0–39% depending on income level — UVT-based brackets, UVT 2026 = COP 49,799). Colombian rates for 2026 apply to income above approximately 1,090 UVT (about COP 54 million / ~USD 14,000) at the lowest bracket of 19%. Colombian tax returns are due in August of the following year (tax year 2026 return due August 2027). The interaction: you pay DIAN on your worldwide income, then claim a Foreign Tax Credit on your IRS return for Colombian taxes paid. Without a comprehensive US–Colombia tax treaty, this credit-based approach rather than treaty-based exemption is what prevents (most) double taxation. An experienced CPA who specialises in US expat taxes — combined with a Colombian contador — is essential after day 183.
The Art. 11 Plan: Non-Negotiable from Day One
US health insurance — whether employer-provided, ACA Marketplace, or Medicare — is not accepted by Migración Colombia as an equivalent to the mandatory Art. 11 plan. Medicare does not provide coverage outside the US (with rare exceptions). ACA plans typically have network restrictions that make them non-functional in Colombia. The Art. 11 plan (Plan Obligatorio de Salud para Extranjeros) is a Colombia-specific insurance instrument required by Migración Colombia for all Visa M applicants. It must be from a Colombian-licensed insurer, issued in the Migración Colombia-required format, with continuous coverage from the date of visa application through the visa validity period. Many US nationals on Visa M hold both their US policy (for trips home, emergency evacuation) and a Colombian Art. 11 — these are complementary, not substitutable. CoVisas activates the Art. 11 on the precise date required by your visa timeline — no gap, no overlap with billing.
Before leaving the US: Obtain Art. 11 plan before visa application (CoVisas — US insurance is not accepted). Engage a US expat tax CPA (familiar with FEIE/FATCA/FBAR). Check FBAR history — if you already have Colombian accounts above $10k, file immediately. Confirm Physical Presence Test eligibility for FEIE (330 days in 12 months).
Upon arrival in Colombia: Get cédula de extranjería within 30 days of visa approval. Open Colombian bank account — disclose US citizenship (FATCA). Register US accounts with FBAR immediately and track daily aggregate balances. Keep 2555 (FEIE) records — day counts, income documentation.
After day 183: Colombian tax residency begins. Engage Colombian contador for DIAN registration and first declaración de renta. File IRS return (Form 1040 + 2555 + 8938 if applicable) + FinCEN 114. No US–Colombia tax treaty — use Foreign Tax Credit (Form 1116) to offset DIAN taxes paid against IRS liability. No Totalization Agreement — self-employed Americans continue paying US SE tax.
